“Most people who live in a former meth house don’t even know it,” he says. “And some hotel rooms have also been contaminated.”
Recently, Morrison was awarded $116,000 from the National Institute of Standards and Technology to research the interactions between building materials and the chemicals used in methamphetamine labs.
Methamphetamine cooks use a potent combination of ingredients, including ammonia, methanol, ether, benzene and reactive metals. According to Morrison, the chemicals penetrate into materials like paint, wood and vinyl flooring and then “slowly come back to the surface over time.”
Morrison is concerned that children who make contact with the surfaces will ingest methamphetamine. Also, he says, lingering methamphetamine can be released into the air, where it bonds with tiny chemicals that are floating around. This means it could be inhaled, even months to years after rooms were thoroughly cleaned.
“We want to be comfortable with the cleaning methods,” Morrison says. “Are these methods sufficiently protective? How much should people be concerned about living in a former meth house?”
Morrison is leading the Missouri S&T study in conjunction with researchers at the University of Texas-Austin. In order to see how the chemicals interact with building materials, they plan to examine samples taken from homes after a bust and clean-up.
According to Morrison, standard decontamination procedures may need to be amended in the future to include additional steps that are more technical.

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
